What was the name of the school literary society J.R.R. Tolkien belonged to as a teenager?

J.R.R. Tolkien belonged to the Tea Club and Barrovian Society, usually abbreviated as the T.C.B.S.

The society formed among pupils at King Edward’s School in Birmingham, where Tolkien studied. Its members met to discuss literature, poetry, and artistic ambitions, often gathering in the school library or at Birmingham’s Barrow’s Stores. Tolkien became especially close to several members, including Christopher Wiseman and Robert Gilson.

The group’s members remained important in Tolkien’s early life, but the First World War brought tragedy and separation. Robert Gilson and Geoffrey Bache Smith died during the war, and Tolkien’s later memories of the society were connected with both youthful creativity and wartime loss. The T.C.B.S. is not the same organization as the later Oxford group called The Inklings.
